Specification of Letters Patent.

Patented June a, 1900.

Application filed October 16, 1906. Serial No. 389,033.

To all whom it may concern:

Be it known that I, Gnonon A. Pos'r, a citizen of the United States, andresident of Chicago, county of Cook, and State of Illinois, ave inventedcertain new and useful- Improvements in Washing Machines, of which thefollowing is a specification and which are illustrated in theaccompanying drawings, forming a art thereof. The invention re ates tomachines fo washing clothing, and particularly to those of that type inwhich a receptacle adapted to be rap d y revolved is rovlded for thearticles to be washed, an .a cleansing fluid is caused to permeate thecontents of the reoepltacle by centrifugal force.

- he mvention contemplates a basin for containing the cleansing fluid, aclothes receptacle mounted for rotation within the basin and having ,aforaminous peripheral wall, and means for raisin the cleansing fluidfrom the floor of the basin to the interior of the receptacle. v

A feature of the invention provides for removing the fluid contents ofthe basin in order that the device may also be employed in the usual wayas a centrifugal drying machine.

-from a base or floor 1 the shell 10 takes the form of a basin havingThe object of the invention is to provide means whereby clothing may bewashed,

rinsed, blued and dried in a single machine without being handledbetween such operations.

is a central vertica section showing a machine constructed according to'the invention; Fig. 2 is a plan view, artly broken awa of the samemachine; 1g. 3 is a sectional detail taken on the line 3-3 of Fig. 2;Fig. 4 is a sectional view on the line 4 4 of Fig. 1.

A cylindrical shell 10 is rovided for the operative parts of themachlne, andis prefera ly carried by standards, as 11, 11, rising plate12. As shown,

av floor 13 which is downwardly incline toward its center and isprovided with valved pipes, as 14, 15, for the introduction of thevarious fluids employed in treating the articles. to be cleansed,andwith a valved drain-opening 16. The side walls of the shell or basinare flanged inwardly at the top, as indicated at 17, and aremovablecover 18 is applied thereto. 1

A clothes rece tacle 19 is rotatablymodnted within the asin, beingpreferably se- In the accompanying drawings, Figure 1' cured to a shaft20 which is stepped in the base plate at 21 and extends u wardly throughthe floor of the basin. As s own, a roller bearin 22 is provided for theshaft in the floor of tile basin, and a packing gland 23 is ap lied toone end of the bearing to prevent eakage. The side walls of thereceptacle 19 are freely perforated, asindicated at 25, to permit theescape of water by centrifugal force, and the upper mar ins of its wallsare flanged inwardly, as indicated at 26, to revent the contents of therace tacle from eing thrown over its sides. or driving the rece tacle abelt pulley 24 is preferably mounte on the shaft 20 below the basin.

Provision is made for the admission of water from the basin 10 to thereceptacle 19 adjacent its axis of rotation. For this purpose there isshown a plurality of openings 27 formed in its floor, and for eachopening there is preferably a lip 28 which projects downwardly at anangle from one ofthe side edges of the opening to form a chute fordirecting water from the basin through the openin to the interior of thereceptacle. Prefera 1y, also, a stand-pipe 29 rises from the floor ofthe basin at its center for delivering water to the interior of theclothes receptacle 19. As shown, it is provided at its foot with aplurality of intake openings 30, and the floor of the receptacle 19 1ssocketed, as indicated at 31 to fit over the head of the pipe and toprovide a nozzle for the discharge of water from the pipe to theinterior of the receptacle. This nozzle preferably comprises a pluralityof pipes 32 which extend radially outwar and upward from the walls ofthe socket 31 and have their outer ends united by arin 33, which has aplurality of circumferential 'y arranged eduction ports 34.

An Archimedean screw 35 is mounted within the stand pipe 29 for raisingwater from the floor of the basin to the discharge openings 34 of thenozzle. As shown it is formed u on a sleeve 36 which incloscs a portionof t e shaft 20, and is firmly secured thereto by means of a cotter pin37.

To arrest the circumferential movement of the water delivered from theside walls of the rotating receptacle 19, and to direct it toward the,center of the basin 10, a plurality of baffles 38 are formed. on 'theside walls of the basin. As shown tlfese liafllcs are continued alongthe floor of the basin to the stand pipe 29, and each joins the wallsof. the stand pipe at the side of one of the openin 30 at its foot.Preferably that parteach of the baffles which extends along the floor ofthe basin is formed in a curve inclined to a radius of the basin, asindicated at 39, Fig. 2, and is provided with 19, while still ry, andthe machine given a few revolutions at a high speed before any of thecleansing water is introduced in order that the clothing may becomecompacted against the side walls of the receptacle 19 Without tanglingor tearing. Water for cleansing, rinsing and bluing the articles willthen be introduced in succession through the valved pi es 14, 15, asuificient quantity being prefera ly employed in each case to fill thebasin 10 to a depth adapted to cover the floor of the receptacle 19 whenthe ma- .is. still in motion.

chine is at rest. 'By means of the screw 35 Within the stand pipe 29 andthe inclined lips 28, water will be delivered to the interior of thereceptacle 19 when it is rapidly revolved, through the openings 34 and.27, respectively, and will be thrown by centrifuf gal force upon theclothin compacted against the peripheral wall of t e receptacle} Onpassing through the clothing, it will be delivered to the side walls ofthe basin through the openings 25 in the walls of the race tacle 19, andit will then be directed by the affles 38 to the center of the basin.From this point it willbe again drawn into. the receptacle by theArchimedean screw 35, and a continuous circulation of the fluid contentsof the basin is thus maintained. After one or more of the washingoperations have been completed-in the manner described, the clothingcontained Within the receptacle 19 may"be thoroughly dried by openingthe valve of the drain-pi e 16 while the machine he excess water held bythe clothing will'then be thrown by centrifugal force a ainst the sidewalls of the basin from whic it may escape through the drain-pipe. 1;
